Osteoarthritis of the knee is a leading cause of disability in the world, especially among the elderly population. In the United States, multiple common risk factors, such as increasing average age and obesity, have led to a rise in knee osteoarthritis incidence. As such, novel therapies and treatments that can slow down, halt, or even reverse the progression of disease are in high demand, and biotech and pharmaceutical companies are continuing to design clinical trials that test the safety and efficacy of new products.

Imaging plays an important role in the design of such clinical trials, as selecting the appropriate imaging modalities, assessments, and endpoints are critical to conducting a successful study. Imaging can be leveraged as part of the subject selection process to identify osteoarthritis phenotypes and to stratify patient populations that are appropriate for a trial. Depending on the type of treatment, imaging assessments can also be designed to focus on the structural correlates of pain, or to evaluate structural changes in cartilage and bone for disease modification claims.

In the first half of this webinar, Dr. Timothy Mosher will provide attendees with a basic understanding of the common imaging modalities for evaluation of knee osteoarthritis and how imaging can be used for subject selection and evaluation of the investigational product for two types of knee osteoarthritis clinical trials: treatments focused on symptom modification and treatments focused on cartilage repair.

In the second half of the webinar, Dave McGurl and Iman Ahmad will discuss endpoint design and other regulatory considerations for those two scenarios, as well as the importance of properly monitoring sites for imaging protocol compliance and image quality throughout osteoarthritis clinical trials.

Register for this webinar to learn how imaging can be leveraged for knee osteoarthritis clinical trials focused on symptom vs. structural modification, and the practicality and implementation of common X-ray vs. MRI assessments.



Timothy J. Mosher, MD., Kenneth L. Miller Chair, Department of Radiology at Penn State University; Radiologist Consultant and Faculty Director at Medical Metrics, Inc.

Dr. Mosher is the Kenneth L. Miller Chair, Department of Radiology at Penn State University and Distinguished Professor of Radiology and Orthopaedic Surgery.
